The device of: my. invention is used for inl troducing `material intovvafeonduit' ,through whichuid under pressureis passingxf The:

Thel airis deliveredby ythe high'p'resstire blower into the` receiver 3 in; which: the f in'ijoulsesf are smoothed outu and the air ps assesy kfrom vthe receiverylthrough the con` which ispreierahly `cylindricad in form and whichisclosed atvthe sides. by the vplates 8.

Journalled infthe Vplatesl 8f ashaft 9' to duitzt.. The conduit 4isprovided with a; `l' 5 which has anI upwardly Adirected opening' whichis secured a pocket wheel 12. The shaft is rotatedV by any suitablemeans such as the electric motor 13 Whichis connected to the shaftthrough a suitable gearingvM. The casing 7 is provided on its upper'side with an inlet opening 15 which is in cominunication with thedischarge spout 16 of a superposed hopper, in which the material p0 be1introduced into the conduit is accumuatec.

it may consist of any other material which it is desired to introduceinto the conduit.

The pocket wheel 12 is preferably closed at the sides by the walls 17-18and is open at its periphery. The pocket wheel is provided with a seriesof pockets 19 deiined by the walls 21 extending` from the hub to theperiphery of the wheel. The material is introduced into these pocketsthrough the inlet opening 15 and, by the rotation of the Wheel, thecharged pocket is moved to a p position over the discharge outlet 22 ofthe casingA and the material is discharged into the T 5. Means areprovided for introducing air under pressure into the bottom of thepockets immediately before they open to the discharge outlet 22 tofacilitate the discharge of the material from the pockets. This meanspreferably comprises a second series of pockets 23 in the pocket wheel,the

two series of pockets being separated bythe intermediate wall 2i. 'Thepocket are defined by walls 25 extending from the hub of the wheel toits periphery. K c c The series of pockets 19 are connected to gether inpairs with the series of pockets 23, one pocket 19 and onepocket forminga pair. The pocket 2B of eachpairleads the pocket 19 so that advance ofthe pocket 19. Azrraiigedlin thecasing 7, in alignment with the`intermediate wall 2&1 is an annular wall 2G, and arranged in alignmentwith this wall 26 and extending kdownwardly into the T 5 is a bai-Hewall 27 whichseives to direct air from 4, upwardly into the pocket 23,asthese the conduit pockets, successively register with the dis* chargeloutlet 22. ,Y l i The series of pockets 19 arev conncctedttogetlier inApairs with the series'of pockets 23 by apertures 28 extending throughthe inten mediate wall 2e at the bottoms of 'the pockets.` As the pocketwheel 12 rotates, a pocket 23 of one pair moves yinto communication withthe discharge outlet 22 inradvanceiof the other pocket 19 of the pair.Air under. pressure is then introduced into the pocket 23 and this airpasses through the opening 28 into the associated pocket 19, at thebottom of the charge of material therein, loos` ens this charge ofmaterial and places it under a pressure which is equal to or greaterthan the pressure to which the pocket 19' This material usually consistsof VWood shavings, sawdust and chips, although Y the pocket v253 comesin communication withthe outlet opening 22 in will be exposed when suchpocket reaches the discharge outlet 22. Consequently,as soon as thepocket 19, which carries the material, reaches the discharge outlet 22,the material in the pocket falls by gravity through the dischargeoutletinto the T 5. The pockets 19 are much wider than the pockets 23and, while the pockets 23 may receive some material at the inletopening15, this material is-blown through the opening 28 into the correspondingpocket 19, when the pocket 23 is exposed at the discharge outlet 22, sothat all of the'material is readily discharged from the pockets as thewheel rotates. By placing the material iii the pocket under a pressuresubstantially equal to the pressure which exists inthe conduit, beforethe pocket comes into communication with thecoiiduit, the liability ofthe material being packed into the bottom of the pocket by the pressureof air entering the opening ofthe pocket is eliminated and all of thematerial is discharged from the pocket during the time that it is incommunication with the discharge outlet.
